Aluminum alloys are sensitive to high temperatures. They tend to lose some of their strength when exposed to high temperatures of about 200-250°C.
Alloy steels comprise a broad spectrum of steels whose compositions are more than the limitations of C, Mo, Cr, Va, Mn, Ni, Si, and B which have been fixed for carbon steels. These steels are more responsive to mechanical and heat treatments than carbon steels.
Alloy or alloyed steels are defined by the ISO specification 4948/1 in the following manner. Alloy steels are those containing any element listed below in a quantity equal to or greater than the quantity for that listed element.
Aluminum alloys have excellent corrosion resistance. They are sensitive to high temperatures in the range of 200 to 250°C (392 to 482°F), and could lose some of their strength.
